Question

what was the work of airplane mode in mobile ​

Answer 1

Answer:

Whatever device you're using—an Android phone, iPhone, iPad, Windows tablet, or whatever else—airplane mode disables the same hardware functions. ... You won't be able to send or receive anything that depends on cellular data, from voice calls to SMS messages to mobile data.

Answer 2

Just click that little airplane and all transmitting will be disabled. You'll also notice that your wifi has been turned off and that your phone is no longer transmitting a radio signal. If you have an Android phone, the process is similar - just swipe down from the top and switch on airplane mode.

I hope it help you...
